easy stuff really  there's a similar thing on JSS ( http://www.javascriptsource.com).
If you can use PHP, it's really easy to do. I just recently did something like what your on about.
If you know any JS, You shouldn't really have too much problem doing it yourself really though  just remember to give yourself 2 text boxes (<INPUT>) and one list menu (+,-,*,\) then make it so that the JS gets the first variable uses the second variable (+,-,*,\) with the last variable. (ie (PHP) $1box $opt $2box)
I've made a few calculators this way (VAT calc, currency converter etc). if you don't mind using PHP, I could make a really quick script...
